Application filed August 7, 1923. Serial No. 656,226.

, Broiling, Cooking, and Toasting Foodstuffs,

of which the following is a specification.

This invention relates to improvements in appliances for broiling, cooking and toasting foodstuffs, and more particularly to improvements in cooking appliances of that type which comprises a frame detachably supporting a broiler device having grooved I grid bar's anda catchment trough for fat, and a heat radiating element or elements for the toasting of bread or similar foodstufls.

The use of cooking appliances previously devised and of the type hereinbefore outllned has been attended by many disadvantages, amongst which are (a) the liability of the grids to buckle due to the fact that they were fixedly mounted in a grid frame and consequently no proper provision was made for expansion and contraction of the grids which receive the maximum amount of heat, (6) the absence of provision for interchangeably fitting broiling grids, (0) the lack of means to conduct excessive smoke from a kitchen or like culinary department, and (d) the absence of satisfactory means which will ensure that overflowing fat exuded from the foods being broiled will dripiat predetermined points and prevent fouling of the appliance.

The present invention has been devised to remedy the above and other defects incidental to the use of cooking appliances of the type hereinbefore mentioned, and it provides a cooking appliance which will effect considerable. economy in fuel consumption and obtain a maximum efficiency when used for broiling, cooking of foodstuffs.

The invention consists of the features of construction, combination and arrangement hereinafter fully described, reference being had to the accompanying drawings, wherein Fi re 1 is a view in perspective of a broiling, cooking and toasting appliance embodying my improvements.

The broiling, cooking and toasting ap pliance according to the improvements comprises a main body or shell 5 which is formed in three interfitting sections 6, 7 and 8 that are of rectangular shape and arranged one above the other.

, The uppermost body section 6 isfurnished with an inwardly projecting flange 9 upon which is detachably supported a rectangular-shaped griller or broiler frame 10 having four vertical walls 11 and furnished at its front end portion with a com artively deep catchment well or trough 12 a apted to receive and collect any fat or liquid exuded from the food whilst it is being cooked. This griller or broiler frame '10 is designed to detachably support a grilling or broilinggr'id 13, and for this purpose said frame is constructed having two longitudinally arranged flanges 14 which project inwardly from the side walls 11 and are arranged at a required incline from the horizontal so as to impart sufficient inclination to the grilling grid 13 to enable the fat or liquid to flow freely intosaid catchment well 12.

Grooves or channels 15 are formed longitudinally in said flanges 14 and they function as collecting chambers for any surplus fat, conducting it to the catchment well or trough 12 and preventing it from foullng or running down the sides of the appliance. A grooved flange or ledge 16 is formed transversely across the griller frame 10 at the rear of the catchment well 12 and it isadaptedto'support the front end of the grid 13.

The detachable grilling or broiling grid 13 is constructed substantially in corrugated form so as to provide longitudinal grooves underside of said grid 13 and function as flange 31 formed dn the lower section 8 of means for preventlng the fat, overflowing the body or shell of the appliance. This from said grooved gr1d bars, from coursin plate is located beneath the fuel burners uninterruptedly along the underside thereo 29, and it functions to radiate heat to a The said ribs 19 also strengthen the grid toasting grid 32 of approved design, which is 13 and prevent same from buckling under slidably inserted into the lowermost section 'execessive heat conditions.

A heat with intermediate heat collecting chambers.

radiating plate 30 of sim1lar construction This plate soon becomes heated to a highto the radiating plates before-mentioned is temperature degree, and heat is radiated detachably and reversibly supported upon a therefrom. Simultaneously heated air passes through the slots 24 formed at the upper portions of said heating chambers into the sinuous passage 26 that is disposed between the upper and lower located plates 21 and 22, respectively. The upper of said plates, by reason of its corrugated formation, also provides a series of chambers with appropriate baflies, and the heat radiated from both of said plates, and the heated air that is conducted upwardly soon transmits ample heat to the detachably mounted grid 13 for the broiling of meats or other foodstuffs. Simultaneously the corrugated plate 30 disposed below said fuel burners becomes heated, and it radiates heat sufliciently to toast sliced bread or like foods supported upon the toasting grid 32.

The water contained within the tank 35 improves the quality of the toasted bread or like food, and as it becomes heatedit may be utilized for culinary purposes. I

The fat and liquid exuded from the foods supported on the corrugated grid 13 heated in the manner described, are initially collected by the grooves 17 and delivered gravitationally to the catchment well 12. Any surplus fat, which may overflow said grooves, passes through the slots 18, formed in the ridge portions of the grid, and courses along the undersurface of the grooved portions of the grid until interrupted by the ribs 19, which thereby function as baflies and dri points.

ny fat dripping from the ribs 19 and not consunied by the heat arising from the corrugated radiating plates 21 and 22 descends onto the upper of said corrugated radiating plates to be consumed by the heat thereof. Fat overflowing from the opposite sides of the corrugated grid 13 is collected by the channelled ledges 14, which are in communication with the catchment well 12.

Should fat be-collected in such quantity as to overflow the grooves of the upper heat radiating plate 21, it passes through the slots 24 and is caused by the projections 25 to drip into the channels of the lower heat radiating plate 22, where it will be positively consumed.

In some cookingoperations and when it isdesired that a more even" distribution of heat should-take place through the upper and the lower located sections of the appliance, one of the corrugated plates 21 and 22 may be reversed in position as is seen in Figure 5.

The ease with which detachment of the sections 6, 7'and 8 and the reversible corrugated plates 21, 22 and '30 can be effected provides for ready accessibility to the various integers of the appliance for cleansingas also for repair or replacement purposes.
